We are all about finding new and unique ways to get moving. Sometimes, it's nice to do workouts that you're comfortable with—other times, it feels good to push your body and take on a new challenge. If you're in the market for the latter, prepare to be inspired by Victoria's Secret models Jasmine Tookes and Josephine Skriver lifting themselves into a one of the most impressive partner workouts we've seen.

The video comes with some simple instructions in the caption: "Grab your bestie and do this partner ab workout! One does the sit-up and one does the plank to pike! Do 20 reps and then switch for another 20 reps!!" (20 reps?!)

The two models, who share an Instagram account devoted to fitness, aren't quite your average weekend warriors. Twenty reps of any move is a lot to ask, let alone an exercise where your bestie's life and face are in your hands. But this pose is so impressive that we had to find out how it's done—and more importantly, how we could attempt it ourselves.

"This is a hard move. l think it's important to know your limits before attempting such a challenging workout," certified fitness trainer Nadia Murdock tells SELF. "To successfully complete this move, both parties would need an adequate amount of core and upper-body strength." First, watch Skriver do a sit-up, rolling up to almost 90 degrees. Then watch the video again, focusing on Tookes as she moves from a plank to a pike-up with her core engaged throughout.

"This involves a a full sit-up and pike-up, with real bodyweight added," says trainer Monique Crouse, senior instructor at bodē nyc. Taken on their own, each of the move's components isn't so scary. But together, they involve serious strength, core control, and coordination. "Balance, core, and upper-body strength weigh heavily on the person on top," Murdock tells SELF. They key to getting your limbs as controlled as JoJa's (and making the move look so graceful) lies in keeping your core engaged, as well as your glutes and leg muscles.

Before you attempt to hoist up a partner yourself, Murdock recommends making sure you can do a few basic movements first. Test yourself by attempting a plank, with your arms fully extended, for at least 1 minute. "If you are unstable holding the elevated plank position, it's likely you cannot properly complete this workout or worse, may put yourself at risk of injury," says Murdock. Another test: Try a weighted sit-up with a dumbbell or kettlebell before you attempt to pick up your workout buddy.

Eventually, once you can hold a plank steadily and do a few weighted sit-ups with ease, add a partner. Murdock has one more caveat: If you're someone who experiences any type of vertigo, you may want to find another fitness feat to tackle. "This is not the move for you until you have been treated," Murdock says.

Last but not least, make sure to thank the Josephine to your Jasmine...and get the whole thing on video.
